Richard, to set you straight a bit the power supply can supply up to 100 amps. it does not matter how much current the supply can supply the beagle will draw up to 1 amp if you are flashing the Emmc the beagle runs fine on the 500ma USB power supplies as long as you are not flashing the emmc. http://elinux.org/Beagleboard:BeagleBone_Black_Accessories#Power_Supplies http://www.adafruit.com/products/276?PageSpeed=noscript https://www.sparkfun.com/products/12889 http://www.logicsupply.com/pw-5v2a/
these are known to work well with the BBB there are countless others out there i personally use a 5v 700ma phone charger on one i have plugged into the USB port and a 1a one i had shipped over 2 years ago from china for 3 dollars free shipping on another. if you plan on loading up with capes you will need even more current. pardon me if i misunderstood your email. but a 2amp wall wart is just fine On 5/28/2015 12:48 PM, rh_ wrote: > On Thu, 28 May 2015 06:27:56 -0700 (PDT) > Dennis Kerrisk <dennisk8...@gmail.com> wrote: > >> No using a 5V 2A wall wort. > This may be the problem.
